1/8 of passengers of a train were children. if there were 40 children travelling in the train on a certain day, how many adults
lilavasa [31]

280 adults were there in the train.

What is linear equation definition and example?

  • The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line.
  • An example of linear equation is y=mx + b. noun. 20.
  • A polynomial equation of the first degree (such as x = 2y - 7)

Given,

      Total children are in the train = 40

     1/8  are children in train and no of children in train ,

      ∴ 1/8 × x = 40

     x = 40 × 8 ⇒ 320

The no of  passenger in train  = 320

in total passenger, 40 are children .

So, rest adults passengers are = 320 - 40 ⇒ 280

There fore, 280 adults were there in the train.
